Topological magnon noises
Shuang Liang, Tengyue Zhao, Yu-Hang Li +1
We develop a comprehensive formalism for magnon transport in ferromagnetic insulators driven by a temperature gradient. The formulas for magnon current and corresponding magnon noi…
Superconducting triode effect in a quantum-dot Josephson junction with a biased top gate
